Inventor: MIYAKE HIROSHI
IPC: H01L21/26
Filed: 2019-11-18
Abstract: To provide a heat treatment apparatus in which change of color of a gas ring can be prevented.SOLUTION: A gas ring 90 is mounted in upside of a chamber lateral 61 which is a sidewall of a chamber 6. The gas ring 90 is configured by superimposing an upper ring 91 and a lower ring 92 one on another. A clearance between the upper ring 91 and the lower ring 92 provides a flow passage 97 of processing gas. A resistance portion having labyrinth structure is formed in the flow passage 97. Heat capacity is increased by increasing a mass of the lower ring 92 including an inner wall surface 92a. The lower ring 92 is attached to the cooled chamber lateral 61 in a surface-contact manner, so that thermal conductivity from the lower ring 92 to the chamber lateral 61 is improved to a large value, and a heat quantity to be stored in the lower ring 92 is reduced. Thus, rise of temperature of the lower ring 92 during heat treatment is suppressed, thereby preventing the change of color of the gas ring 90 can be suppressed.SELECTED DRAWING: Figure 11

Title: Slot machine
Inventor: OGURA TOSHIO
IPC: A63F5/04
Filed: 2019-11-22
Abstract: To provide a slot machine having an improved configuration of suggesting an operation mode.SOLUTION: When it is determined that all reels under rotation control are rotated at constant-speed rotation, a main control section validates reception of stop operation of all the reels under the rotation control and, when detecting a valid stop operation, can stop a corresponding reel. Alternatively, after display data is set to an output buffer of a game assist display, until the display data is erased, the main control section can execute control of displaying a display content based on the display data on the game assist display by timer interruption processing. Each time it is determined that all the reels under the rotation control are rotated at the constant-speed rotation, the main control section acquires a navigation number from a navigation number setup area of RAM, converts the acquired navigation number into display data for every display, and repetitively sets it to the output buffer of the display.SELECTED DRAWING: Figure 13
